Two-dimensional domain structures are normally formed at the air-water interface due to phase separation in mixed monolayers, in which their components are incompletely miscible. This provides us a chance for studying some quasi-two-dimensional phenomena in physics, such as phase separation and phase transition. On the other hand, mixed monolayers provide us a way of assembling several kinds of functional molecules into

Nile Blue can strongly bind to DNA and its affinity for DNA has beeninvestigated by spectroscopy and spectroelectrochemistry. At low DNA concentrations, Nile Blue canbind to DNA (per nucleotide phosphate) to form a 1:1 association complex with the binding constantof 4.7 * 10~4 L/mol and the major binding model of Nile Blue to DNA is 'electrostatic binding'.However, the major binding model changes into 'intercalative binding' at high DNA concentrations. Inorder to confirm which part of Nile Blue intercalating into DNA, the inclusion action ofβ-cyclodextrin (β-CD) has been used to study the interaction. Nile Blue can be included into thehydrophobic cavity of β-CD to form an inclusion complex with a stability constant of 1.9 * 10~3L/mol. The experimental results indicate that the naphthalene ring part of Nile Blue is includedinto β-CD's hydrophobic cavity and the inclusion complex decomposes at high DNA concentrations. Itmay be deduced reasonably that the naphthalene ring part of Nile Blue molecule intercalates into DNAhelix Strand.

The p nitrophenylazo calixarene derivatives 1a-1d with nonlinear optical (NLO) properties were prepared by the diazo coupling reaction of calixarene with p nitrophenyl diazonium. The diazotization reaction of p nitroaniline was carried out with isoamyl nitrite as a source of nitrous acid in EtONa/EtOH under refluxing condition. X Ray crystallographic analysis and 1H NMR spectra reveal that they exist as cone conformation in crystal state or in solution. HRS measurements at 1064 nm in THF indicate that p nitrophenylazo calixarenes have higher hyperpolarizability β z values than the corresponding reference compound 4 (4 nitrophenylazo) 2,6 dimethyl phenol, without red shift of the charge transfer band. The tetrakis p nitrophenylazo calixarene (2) with longer alkyl chains can form monolayer at the air/water interface.

SrGa-2S-4∶Ce blue TFEL device with a novel structure was prepared by electron beam evaporation. The dielectric constant of insulator layer in this structure is far less than that in the conventional structure, so the hot-electrons can be accelerated in SiO-2 layers. The stable TFEL with good chromaticity was achieved and the basic characteristics were investigated.
